The cement ball mill is a horizontal cylinder filled with steel balls or other grinding media. Inside the cylinder, the steel balls are rotated and tumbled and crush the clinker into very fine powders, which are product cement powders. During the grinding process, a small percentage of gypsum is added to the mix to control the setting time of ...

preheater used to be 500 to 550 mmwg. Any increase in number of stages resulted in additional pressure drop which unfavorably offset gain in fuel efficiency. Therefore cement industry continued for quite some time with 4 stage preheaters till cyclones of low pressure design were developed. Attention

17 4.Grinding system Ball mill is the earliest grinding equipment used in cement production industry, and it still plays a leading role. Although its efficiency is very low, for example, the power consumption of single particle is only 6% - 9%, the maintenance of ball mill is simple and reliable, especially for cement clinker grinding.

Preheater and precalciner kilns are shorter than a long cement kiln and contain tall preheater towers that use the heat produced by the kiln to caloine the raw materials as they move through the various stages of the tower. These kilns reflect the latest in cement kiln design technology.

Cyclone Preheater Introduction: The cyclone preheater is the core equipment of the new dry process cement production technology.It uses the suspension preheating method to preheat and partially decompose the raw material to shorten the length of the rotary kiln, and at the same time make the raw material and the hot gas flow in the kiln full.

It's the heart of the cement making process—a horizontally sloped steel cylinder, lined with firebrick, turning approximately four revolutions per minute. The kiln is the world's largest piece of moving industrial equipment. From the preheater, the raw meal enters the kiln at the upper end.

Precalciner is also called cement calciner. Calciner in cement plant is mainly used for the pre-decomposition of cement clinker and forms the clinker calcining system in the new dry process cement plant together with preheater, cement rotary kiln, and cement cooler.

The Features of Preheater: (1) The upper feeding system: Includes the upper hopper, the next material possession, the next feeding method and structure can guarantee to the pre-heater of the body feeding to achieve security when closed, so that the cold air from outside can not enter into the preheater, and feeding can make use of valve rod to achieve continuous or intermittent feeding.
